To realize its value correctly, that is, people or regions that are useful to this information can fully get this information, that is, the universality of information.
Question 2: How to judge the value of information and how to identify and evaluate information.
First, the teaching object analysis:
In the process of information acquisition, there is always the problem of how to identify and evaluate information, which is easy to disturb people's attention in the complicated information world. Therefore, it is particularly important for teenagers to learn to accurately identify and evaluate information.
Second, the teaching objectives:
1, can identify and evaluate information and master the basic methods of information value judgment.
2, can form a keen insight into information, can have a strong ability to distinguish the authenticity of information, can identify and * * * bad information.
Third, the teaching focus:
Master the basic methods of information value judgment.
Four, teaching difficulties:
Can form a keen insight into information and have a strong ability to distinguish the authenticity of information.
Five, teaching methods:
The combination of explanation, inquiry, task-driven and autonomous learning.
Sixth, the teaching process:
In the information age, information has brought people great material and spiritual wealth, but all kinds of information are complicated, confusing and difficult to distinguish between true and false. Therefore, effective identification and evaluation of the obtained information is the premise of using information.
So how to identify and evaluate the value of the information obtained? We will discuss this problem in this class.
1) Method of identifying information from the source:
Case study:
Case 1: After registering personal basic information online, Li Ming received an airmail from abroad, saying that he won a cash prize of 230,000 yuan. As long as he telegraphs the handling fee of 150 yuan immediately, the cash can be delivered to him within two days.
Query analysis:
(1) Where did Li Ming get the winning information? Is the information source reliable? Why?
(2) Is there anything suspicious about the winning information itself?
(3) Li Ming asked the bank if the information provided by the bank was reliable.
(4) Besides the follow-up investigation by the public security organs, is there anything else that can distinguish the authenticity of the winning information?
(5) Evaluate Li Ming's behavior of leaving real name, address and other information on the Internet. Would you do that? Why?
Case 2:
June and July each year is the peak period for college students to find jobs. In the face of overwhelming recruitment information, how to quickly and accurately identify the true and false information and prevent being deceived.
(1) Pay attention to whether the information elements released by the recruitment department are comprehensive.
If the company name is not published, it is likely that the company is not legally registered.
(2) Long-term released recruitment information
For example, some information is published in newspapers or evening papers almost all the year round, and it is well paid. The authenticity of this recruitment information can be imagined.
(3) Pay attention to whether the employer only leaves a mailbox or a post office box.
Individual illegal intermediaries use recruitment gimmicks to obtain a large number of personal information of job seekers and make profits by selling their personal information.
(4) Pay attention to whether the recruitment volume of the recruiting unit is too large and whether the number of recruits is too large.
Summary:
1, check the information source and judge whether the information elements are complete.
2, logical reasoning, consultation and investigation methods for textual research and in-depth investigation.
3. Whether the information source comes from the authoritative department.
4. Judge whether the things involved in the information exist objectively and whether the various elements that make up the information are true, and compare them with similar information.
5. Study whether this information is representative and universal.
6. Field trip.
7. Learn to analyze and identify, discard its dross and take its essence. Good at learning and thinking. Beware of being cheated.
2) From the value orientation of information.
One can't accept all the information. He only cares about information about himself, because it is valuable to him.
The value of information is different for everyone. For us, the information we get in our daily life is useful, useless, true and false. Therefore, due to different social roles, different knowledge backgrounds and different life experiences, the diversity of information value orientation is determined.
Case study:
Example 1: Different people have different views on the problem of world famine.
(1) Reporter: Report the direct consequences of food shortage in time, including casualties, current national and regional rescue activities, food aid and transportation, and ongoing rescue action plans.
(2) Historians: study the history, geography and population of a country or region, and determine various factors that cause current hunger. To examine the face of each country, we should not only determine the above factors, but also understand the birth rate and mortality rate, life expectancy of men and women, moral standards of children and other relevant important statistical data of each country.

Question 3: Judging the value of information can be judged by its attributes. Under the condition of market economy, information has become an extremely important commodity. The information society is usually defined as the concentration of information production and consumption. Information concentration depends on the demand for information and the degree to which this demand is met. Therefore, one way to observe whether the information society is formed is to evaluate the intensity of information exchange and the persistence of information internal flow. So, what is information value? How to determine its value? These problems have become one of the most basic problems facing the information society today. In recent years, behavioral economics has combined economic theory with psychological theory to study the subjective value of information and achieved certain results. These research results have important enlightenment for us to understand the decision of information value and the characteristics of people's information demand under the condition of market economy.
Question 4: How to measure the value of information? How can we correctly realize its value? The value of information is equal to the income that information can bring minus the cost of collecting information. The value of information cannot be measured correctly and varies from person to person.
Question 5: Can the intrinsic value of information be measured by the amount of information? So, how to measure the amount of information? The amount of information cannot be measured by the number of times messages are obtained, because there may be thousands of messages entrusted with the same content; It can't be measured by words. No matter how many words there are, they are all nonsense and the amount of information will not increase; The amount of information has nothing to do with the sound intensity, such as turning up the radio to get information.
Question 6: The criterion for judging the value of information is just like the value of ordinary goods will affect people's consumption of the goods, and people's feelings about information (subjective value) will affect their demand for it, so this is an important influencing factor in the information society. But information is different from ordinary commodities, and it is difficult to evaluate because of its unique characteristics. Information is not an ordinary commodity in production, distribution, cost and consumption. Information is not only a finished product, but also a tool or input for other commodity decision-making. At first, the production cost was high, but the reproduction cost was low. In fact, its replication is mainly accomplished through replication. A kind of information can be spread through different media, and its value is often obtained from this media rather than from the exchange value of the information itself. On the other hand, information will not be reduced because of consumption. The way people consume information is to share public information with others and buy other people's private information, while most other goods are consumed through purchase. The cost of information may be direct or indirect. Because information is an empirical commodity (meaning that information can only be obtained after consumption), the evaluation of information value is very complicated. 1986, Ahituv and Neumann summarized three provisions about information value in the book Principles of Management Information System: standard value, actual value and subjective value (Ahituv and Neumann, 1986). The following three provisions are examined one by one. First of all, because information is an empirical commodity, its value only appears after use (Shapiro and Varian, 1999). We assume that information has a standard value, but because everyone's experience is different, the judgment of information value will be very different. Therefore, the standard value of information is not unique. In other words, the so-called "standard" has become "non-standard", which in turn reveals that the assumption of standard values is problematic. Secondly, because the reproduction of information is mainly accomplished by copying, the cost and value of information have nothing to do with the quantity of this product. In decision-making, information is the tool or input product of other commodities, so information has a strong indirect effect, so it is not appropriate to directly measure the actual value of information (Alstyne, 1999). The method of measuring the actual value of information is based on the analysis of past economic development, so it will cause the so-called "test paradox" (Van Alstyne, 1999). Therefore, the value of information can neither be the standard value nor the actual value. Information value is a kind of perceptual value and subjective value of information. Obviously, information mainly spreads through two paths: sharing and trading. The tendency of people to buy and sell information and share information is the main determinant of information value. Once people are willing to share some information, its value will be greatly reduced. Therefore, the value of public information is very low or even worthless (here only refers to subjective monetary value). Therefore, it is of little significance to study information sharing.
Question 7: How to measure the commercial benefit of information system and how to evaluate the benefit of information system investment? Dong Li, June 7, 2006 Source: CCW Keywords: Evaluating the benefits of information investment The benefits of information technology are not reflected in the information technology itself. How much money to buy depends on the degree of integration between the purchased IT and the business of the enterprise. The closer the integration is, the more the benefits of information technology can be brought into play. First of all, I want to talk about why we should study the benefits of informatization. Since the 1960s, academic circles have been paying great attention to the benefits of informatization, so many scholars have focused their attention on the benefits of informatization. Let's go back and see why it is so important to study the benefits of informatization. Whether in academia or in practice, people think that the benefits of informatization are mysterious, which seems to be difficult to explain clearly, especially after the development of informatization, when people didn't care much about the real and practical benefits of informatization. When informatization encounters low tide and problems, everyone will doubt its benefits. Let me sum up the first big debate about the benefits of informatization in the past. In the late 1980s and early 1990s, the problem of productivity backup was put forward. At that time, the scholar only studied less than 65,438+000 enterprises in the United States. Later, he found that informatization was not directly related to the final result of this 100 enterprise. He put forward this view. After this view was put forward, many people thought it was not a major discovery, but a small sample. Everyone says it's an information black hole or something. Later, many such words appeared. In 2000, e-commerce encountered obstacles, and another company came out to investigate 53 industries. Only 6 industries were profitable, and others were not, which had a great impact on everyone. Many enterprises are hesitant to invest in informatization, and they should be especially cautious when they regard informatization as a risky project. Second, this article was published in Harvard Business Review last year. When there are no IT people, others have no IT equipment, only I have it. This is my competitive advantage. When everyone has it, it cannot be a competitive advantage. Now we need to control the information cost. This view is not reasonable. The problem is how to treat this problem, especially in view of the current situation in China and the stage of informatization development in China. Many enterprises have introduced it, but it is far from releasing its real potential. For us, we should pay more attention to how to study its efficiency. CIO survey, just as I did a CIO survey last year. I made a survey of more than 300 enterprises in China and sent a questionnaire to the CIO. Finally, I made statistics and extracted the concerns of 10 CIOs. What they are most concerned about is how to combine IT technology with the specific business of the enterprise. The second is the IT security of enterprises, and one of them is information evaluation. How to evaluate the benefits of this information system? The CIO must be clear about this issue. If you don't make it clear, you can't apply for money, otherwise you will be questioned by CEO or CFO when you apply for money. One more question. Enterprises in China have invested heavily in this field. If this benefit is not clear, it will have a great impact on the whole enterprise. How to evaluate informatization? There are many ways. At least forty or fifty papers I have seen have been published in well-known foreign information magazines. There are about forty or fifty well-known methods to evaluate the benefits of informatization. What about so many benefit evaluation methods? There is a thoughtful evaluation, and the basic evaluation is this. Everyone may have realized by now that the benefits of informatization should be divided into two types, one is visible, visible and clear. The introduction of information system reduces the number of employees and saves the time for enterprises to process information, which can be expressed by accurate figures. The other is that you may not be able to express it directly. Many things are hidden, intangible or indirect, and their meanings may not be exactly the same, so there is no way to express these benefits directly. According to the research of many academic circles, their research results show that hidden interests account for most of the effect of enterprise informatization. A professor at MIT said that hidden benefits account for more than 90%. Are there any specific figures to illustrate this point? It's not clear yet. From this perspective, we summarized the benefits of informatization from three aspects ... >>
Question 8: How to realize the value of information correctly? The value of information can neither be standard value nor measured by actual value. Information value is a kind of perceptual value and subjective value of information.
To realize its value correctly, that is, people or regions that are useful to this information can fully get this information, that is, the universality of information.
